1-8 channel integrated multiplexing audio optical transmitter/receiver adopts digital coding technology, and the audio interface is XLR (Canon socket). It can realize long-distance bidirectional transmission of audio signals, data signals, switch signals and Ethernet signals through a single-mode optical fiber, and can transmit the signal without distortion and relay up to 100km. The audio interface adopts 24Bit AD/DA, 128K sampling, and studio-level transmission quality. It can provide +48V phantom power for condenser microphones.
The audio optical terminal is composed of an optical transmitter and an optical receiver, and can be configured as 4-channel bidirectional audio and 8-channel unidirectional audio.
● Fully digital optical fiber transmission platform, flexible configuration of multiple services on the same platform
● 19-inch 1U aluminum alloy anodized shell, IP40 protection level;
● The audio interface is an XLR balanced interface, and the audio power supply is a high-power toroidal transformer, +-18V power supply, high dynamic range;
● It can provide +48V phantom power for condenser microphones;
● It can provide ordinary desktop, mini desktop, centralized card-type rack and other methods;
● The audio interface provides three-level lightning protection function and can pass ITU-T K.21 (10/700 μS), common mode: 6KV, impedance (40 Ω) test;
● Single fiber transmission, optional dual fiber
● It can detect whether the remote device is powered off or broken when there is no light
● The audio uses 24Bit AD/DA, 128K sampling, studio-level transmission quality
● A variety of power supply methods are available: single AC220V, AC+AC; etc. Dual power backup
